A portable power supply consists of a 28 liter bottle of compressed helium, charged to 13.8 MPa at 300K, connected to a small turbine. During operation, the He drives the turbine continuously until the pressure in the bottle drops to 0.69 MPa. The turbine exhausts at 0.1 MPa. Neglecting heat transfer, calculate the maximum possible work from the turbine. Assume helium to be an ideal gas with Cp/R
